IMPROVEMENT IN' DEVICE FOR APPLYING- G-ILDING--PREPARATIONS TO OVALFRAMES.

The Schedule referred to in these Letters Patent; and making part of thename.

To all whom it may concern:

Be it known that I, DAVID GRRIsoN, of the city of Philadelphia, andState of Pennsylvania, have invented certain newvand-useful improvementsin the' manner of making circular or oval insides for circular or ovalframes; and that the following is a' full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 represents, inperspective, a machine, in whichy the insides for oval frames areprepared, and from ywhich it will be obvious how circular insides can bemade in the same way. i

Figure 2 represents one of the oval insides as finished. l Figures 3, 4,5, 6, 7, and 8, show how insides have been heretofore made, and thedifference between such and those I'make. The insides (so termed) inquestion, are made lof pine or other wood, prepared, and gilded, for thepurpose of relieving the sombre color of black walnut, which is muchused for frames, and are placed in the rebates of the walnut frame.

would warp and twist, so that many were broken and.

destroyed in attempting to restore them to their natural, ororiginal-form, or shape.

By my mode of procedure, I avoid the diliculty and expense heretoforeinvolved, and enamel or coat the insides, in parcels, in a machine,` bywhich the operation is not only much expedited, but the work betterdonc, while I avoid the liability of breakage by handling.

A number of these insides is turned fromVV a `block or suitably.prepared board, as shown at a, a, a,

dre., in fig. 5, and are thence placed in an oval or circular ring,-A,which is revolved ou its edge, as shown 'in the drawings, by agear-wheel, B, taking into the cogs on the outer perimeter of the frameA, said frame being held to the gear B by means ot' arms or braces C,which have pins, or studs c in them, that take into grooves e on thesides of said frame, and thus prevent it from leaving the gear.

On one of the arms C there is placed a scraper, b, which is hinged at d,so as to swing it into position or Being of very thin may v terial, ithas always been dliicult to handle them, on, I

out of place, to remove the block of insides when finished. d

The edge of this scraper is so made as to fit into all and thus itremoves all the surplis'of the preparation, while it packs, smooths, andnishes that which will and does adhere to the wood, more perfectly thanit is possible to do it by hand.

The operation can be continued and repeated until satisfactory, and bothsides of the inside, so made, being coated with the preparation, exceptthe small space It, fig. 2, by which the block, or series of insides washeld together, they do not warp, twist, or break, as when coatedseparately, as heretofore done.

When the block, or series of insides is iinished, itis'taken out, andsawed apart, as shown at iig. (i, and cleared of the interposed block orbench betwee 'and ready for use.

Fig. 7 shows a block, of a different gure, or out line, and shownseparated in fig. 8. These, however, arelprepared in precisely the sameway.

The ring, or frame and the series of insides may be oval, round, orparts of each-any form can be turned or revolved ,under a scraper thatis held to it, to press, or work the preparation on to the'wood, or

frame.

The red lines in fig. l show the scraper as swun'g out of itsworking-position, and also show the shape of its lower edge, which isofy course the reverse of the section through the block, or series ofinsides, -and its interposed bench or wood, that holds it together.

The gilding of these insides not subjecting them to any strain orpressure in handling, as. the putting on of the preparation docs, veryfew, if `any of them are broken, and they retain their shape and formfar better than those pre ared separately, as the block shown at iigs. 3and 4 dould be, if even they were prepared bymy machinery.

By my plan, the surfaces'of the whole series are prepared by machinery,except the small portion of Wood that unites them, and forms a bearing'for the scraper, which bearing saves the insides from danger 0fbreaking. I

The small portion of the insides not covered by the material isconcealed by the rebate of the frame in which these insides are used.

I have mentionedgthese insides as being used in connection with walnutframes only. It is obvious that they can be used with any dark wood ordarklycolored wood, as ebony, rosewood, or imitations thereof, l

and, instead of being placed in the rebate only, on the inner edge ofthe frame, they may be placed in a recess or recesses on or in any otherpart of the frame; and,

when so used, the ornament may be placed on the piece so introduced, andthus added to the frame, which is much more convenient'than putting theornament on the frame itself, as it is less expensive.

Bot-h of the sides of my improved inside are equally smooth, anduniformly prepared, while those made by hand were not so, though theywere coated to prevent warping, twisting, and consequent danger ofbreaking.
